Background: Due to its nutrient content, a variety of spoilage microorganisms can grow in bee pollen, especially when handling practices are not appropriate. So, this survey was designed to assess the physicochemical and microbiological properties of bee pollen collected from Bulgaria. Methods: In June 2014, 13 fresh and 19 dried bee pollen samples were collected from Bulgaria. Water activity ...

HPLC analyses of phenolics in the stigma of fruit bearing and fruitless plants of Kigelia pinnata syn. K. africana (Bignoniaceae) was made. The HPLC chromatograms showed higher peaks and higher number (9) phenolic compounds in the stigmas of fruitless plants at Agra. On the other hand, the peaks were low and there were only 8 and 7 phenolics in the stigmas of fruit bearing trees at Jammu and De...

Pollen viability and its germination capability for fruit set in are almond and peach essential. To optimize the pollen culture medium of almond and peach and selection of best medium, the present study was carried out with 48 different culture media containing different compositions including diverse levels of boric acid (0 and 100mg/1), calcium nitrate (0,150and300mg/l،), magnesium sulphate (...

Low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. This study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. In order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...

The effect of high temperatures on harvest index (HI) and morphological components that contribute to HI was investigated in two lines (Bd21 and Bd21-3) of Brachypodium distachyon, a C3 grass recognized as a tractable plant, to address critical issues associated with enhancing cereal crop yields in the presence of global climate change. The results demonstrated that temperatures ≥32 °C eliminat...
